Yes, it's a complete sentence. It's an imperative, urging you to, perhaps, participate in matters relevant to your local community and/or stimulate your local economy. I don't know your context, but I imagine it's something like "Don't travel to the Riviera; go to your local beach. Don't buy cheap foreign knock-offs. Forget the Louvre; go to a nearby museum. Eat at your local restaurants. Join the PTA. Live local."
